After Li Yichen and his team arrived in Hangzhou, they did not rush into action, but instead conducted a detailed investigation of the Gao family.

As the son-in-law of the Jiang family, Li Yichen didn't really know his father-in-law's maternal grandmother's family very well. When Jiang Huashu returned to his roots, many members of the Gao family came. In the years that followed, they only interacted with each other, but Li Yichen never visited the Gao family. The only time they interacted was at his wedding with Shui Shui, when they recognized the Gao family as relatives and received red envelopes.

Jiang Shaoming had the closest contact with the Gao family because he was the eldest son and spent half of his childhood at his grandmother's house. So Li Yichen told Jiang Shaoming about the communication with the Gao family over the phone.

Jiang Shaoming knew about the disappearance of Shui Shui immediately and used his connections in the police to help Li Yichen a lot. However, they agreed not to tell their families about this matter first, so they did not tell Professor Dong.

Zhuang Qiuqiu was the second person after Xingxing to discover that something had happened to Shuishui.

Unlike Xingxing, she immediately spotted the problem with her sharp intuition. The first thing she asked when she called Li Yichen was, "Is there something wrong with Shuishui?"

Li Yichen had worked with Zhuang Qiuqiu many times when he was in the army, but he knew her strength too well. Although she became stupid for three years after giving birth to a child, from Li Yichen's point of view, Zhuang Qiuqiu's physical fitness had only deteriorated greatly, and her mental analysis ability had not deteriorated much.

In the afternoon, Zhuang Qiuqiu successfully boarded a flight from Kyoto to Hangzhou on the pretext of having something to do at her mother's home.

She arrived at five o'clock and saw Jiang Huashu and Li Yichen. Seeing the two people who looked several years older after not seeing them for a few months, Zhuang Qiuqiu shed tears.

"Fourth uncle, don't worry, my sister will find it." Zhuang Qiuqiu was as tongue-tied as he was. He had everything in his mind, but he was not good at expressing his emotions in words.

"Qiu, thank you for your hard work." Jiang Huashu was now completely exhausted. He thought about telling his wife about Shui Shui's disappearance, but he was afraid that Professor Dong could not bear such a big blow.

Qiuqiu's arrival may help them find someone from another perspective.

Zhuang Qiuqiu did not rest and directly contacted her fourth uncle and Li Yichen, listening to them talk about the process of Shui Shui's disappearance and all the recent investigations.

It was not until she heard about her grandmother's family that Zhuang Qiuqiu's first reaction was that it couldn't be them.

But then, she calmly analyzed the situation and decided not to rule out any possibility based on subjective assumptions. As a prominent family in Hangzhou, the Gao family had complex internal relationships and unpredictable conflicts of interest.

All children are different, and no one can guarantee that everyone in a family is good, just like the genetically mutated Jiang Congxue.

Old Master Jiang once said that the Jiang family was red, righteous, generous, and open-minded. Jiang Congxue's personality likely stemmed in part from his maternal grandparents; genetics are no mere rhetoric. Not to mention, the Gao family did have a few bad apples, and perhaps it was these bad traits that were passed down to Jiang Congxue.

"Fourth Uncle, Brother-in-law, I don't think we can jump to conclusions based solely on personal feelings and speculation." Zhuang Qiuqiu expressed his opinion with a serious expression. "Although the Gao family is related to our Jiang family by marriage, and most of them are good people, this doesn't represent all of them. If there are one or two who have been in contact with Jiang Congyou for many years, or even have a cooperative relationship with him, then they will definitely be involved in this matter. Even if it's my maternal grandfather's family, we can't take it lightly. We must thoroughly investigate all possible clues."
